這篇文章主要介紹了Dojo獲取下拉框的文本和值實(shí)例代碼的相關(guān)資料,非常不錯(cuò)，具有參考借鑒價(jià)值，需要的朋友可以參考下
Dojo
Dojo是一個(gè)用javascript語(yǔ)言實(shí)現(xiàn)的開源DHTML工具包。它是在幾個(gè)項(xiàng)目捐助基礎(chǔ)上建立起來(lái)的(nWidgets,Burstlib,f(m)),這也是為什么叫它a"unified"toolkit的原因。Dojo的目標(biāo)是解決開發(fā)DHTML應(yīng)用程序遇到的那些，長(zhǎng)期存在、歷史問(wèn)題(historical problems with DHTML)?？鐬g覽器問(wèn)題。
1、問(wèn)題背景
這里有一個(gè)下拉框，其中選項(xiàng)為一年四季，選中后打印下拉框的值和文本
2、實(shí)現(xiàn)源碼
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>dojo-獲取下拉框的值和文本</title>
<link rel="stylesheet" href="js/dojo/dijit/themes/claro/claro.css" />
<script type="text/javascript" src="js/jquery-1.12.4.js"></script>
<script type="text/javascript" src="js/dojo/dojo/dojo.js"></script>
<style>
#season{
width:200px;
}
</style>
<script>
dojoConfig={async:true,parseOnLoad:true}
</script>
<script>
require([
"dojo/store/Memory", "dijit/form/FilteringSelect", "dojo/domReady!"
], function(Memory, FilteringSelect){
var seasonStore = new Memory({
data: [
{name:"春季", id:"spring"},
{name:"夏季", id:"summer"},
{name:"秋季", id:"autumn"},
{name:"冬季", id:"winter"}
]
});
var seasonSelect = new FilteringSelect({
id: "season",
name: "season",
value: "spring",
store: seasonStore,
searchAttr: "name"
}, "season").startup();
});
</script>
</head>
<body>
<input id="season" /><br>
<button id="valueBtn" onclick="alert(dijit.byId('season').get('value'))">獲取下拉框value</button>
<button id="textBtn" onclick="alert(dijit.byId('season').get('displayedValue'))">獲取下拉框text</button>
</body>
</html>
3、實(shí)現(xiàn)結(jié)果
（1）初始化時(shí)
（2）點(diǎn)擊“獲取下拉框value”按鈕
（3）點(diǎn)擊“獲取下拉框text”按鈕
